U.S. oil reserves fall to lowest level in four decades as Iran conflict drives prices higher

Strategic petroleum stocks in the United States have slipped to a 40‑year low, pushing crude prices above US$80 a barrel and raising concerns for Canadian consumers and investors.

Strategic oil stockpiles have hit a 40-year low amid the Iran war

Oil markets surged on Tuesday after the United States reported its strategic crude reserves had dropped to the smallest volume since 1983. The Strategic Petroleum Reserve fell by roughly 6.1 million barrels to 298.7 million barrels, according to the Department of Energy. The decline comes as the war between Iran and its regional adversaries threatens the flow of oil through the Strait of Hormuz.

U.S. reserves hit 40 year low

The reserve, which can hold up to 727 million barrels, has been drawn down by about 172 million barrels since March. The drawdown is part of a coordinated release agreed by the International Energy Agency to inject 400 million barrels into the market after the United States and Israel launched joint strikes on Iran. With the SPR now at its lowest point in four decades, experts warn that refilling will take years, especially while global supplies remain tight.

Implications for Canada

Although Canada does not maintain a government‑mandated emergency stockpile, the country is a net exporter of crude and a member of the IEA. Higher world prices translate directly into higher pump prices for Canadians. Since the conflict began, gasoline has risen across the country, and the prospect of a prolonged shortage could keep the trend upward.

Canadian investors with exposure to energy markets are likely to see increased volatility. Companies that rely on imported refined products may face higher input costs, while domestic producers could benefit from stronger export prices.

Analysts note that the United States' reliance on its strategic reserves has highlighted the value of maintaining buffer stocks. Canada's policy of not holding a compulsory reserve is unusual among the G7, but the current environment may prompt a review of emergency preparedness, especially if the Strait of Hormuz remains closed.

Oil prices are set largely by expectations of supply and demand. West Texas Intermediate was trading around US$83 a barrel at 3 p.m. Eastern time on Tuesday, up about a dollar from the previous day and well above the low of US$75 recorded last week. The upward pressure on prices is expected to keep Canadian gasoline costs elevated as long as the conflict persists and U.S. reserves stay depleted.
